Answer:
k = -4
Step-by-step explanation:
(k - 10)/2 = -7
First: multiply by 2 to get rid of the denominator
2(k - 10)/2 = 2(-7)
k - 10 = -14
Next: add 10 to both sides to isolate k
k - 10 + 10 = -14 + 10
k = -4

Answer:
121 unit^2.
Step-by-step explanation:
The area = height/2 * ( sum of the opposite parallel lines)
= h/2(BC + AD
h = BF = 14 - 3 = 11 units.
BC = 13 - 5 = 8 units.
AD = 16 - 2 = 14 units.
Area = (11/2)(8 + 14)
= 5.5 * 22
= 121 unit^2.
Answer:
No. Lauren cannot buy the shirt. It costs $48 after the discount.
Step-by-step explanation:
Shirt Cost: $80
Money: $35
Discount: 40%
First, find the amount of the discount by finding 40% of the price. 40% is equal to 0.40 (or 40 divided by 100).
40% of $80 = 0.40 x 80 = $32
Since it's a discount, the final price is the original price minus the discount.
$80 - $32 = $48
So, after a 40% discount, the price is still $48. Lauren only has $35, so it will still be too expensive!
Answer:
two solutions
Step-by-step explanation:
If you have a discriminant value greater than zero (not zero and not negative), you're gonna have two solutions. For zero discriminant, one solution. For negative discriminant, no solutions at all.
Make sure you remember this. It will save you from solving a quadratic equation which has no solutions.
